Adding a Clipping Indicator

[J3M Concepts 10+ year member]

I was looking at a pro-audio board the other day and knowticed an led on each channel to indicate that the input signal of the channel is being clipped.

I was wondering how hard it would be to do that to the outputs of my headunit.

Is it as easy as parallel wiring an led into the rcas or what?

My headunit is rated at 5v peak so would i need a 5v led? Would adding such introduce any kind of noise or interference into the signal?

What do you think?

Much more complicated than that. A clipping indicator is a circuit that actually detects the clipping not just the theoretical max voltage of the circuit.

That's a link to a design for a clipping detector.

Some processors have clipping indicators built in....

INdeed.

Excellent link!

Or you could just buy a maxxsonics maxxlink? Line driver, strapping module, with a clip indicator?

Most processors only tell you when the outputs are hitting the design peak. A few have actual clipping indicators. If the LED isn't labeled "clip" or "clipping" don't assume that it's anything other than a peak indicator. It won't tell you if the input is clipped and won't do squat for the amp output.
